My 5 year old daughter loves lego friends and I love the way they get her imagining and playing. We have to help her build the bigger sets, but she is able to do the smaller ones. Once built, she does a lot of imaginary play and interacting, but then also begins to create new stuff to interact with it, and for 5 years old I am really happy with how much these get her creating on her own. I will be adding to out collection over time.
